Rotate (Clock-Driven Logic)

Last Modified: September 10, 2016

Rotates the specified input (x) the number of specified bits (y).

y

The number of bits to rotate x by.

If y is greater than 0, the node rotates x left y bits in the positive direction (from least significant to most significant bit) and inserts the high-order bits in the low-order bits. If y is less than 0, the node rotates x right y bits (from most significant to least significant bit) and inserts the low-order bits in the high-order bits.

datatype_icon

x

An input to this operation.

If x is an 8-, 16-, 32-, or 64-bit integer, then for any value of y, y ± 8, y ± 16, y ± 32, or y ± 64 yields the same output value, respectively, as y.

For example, if x is an 8-bit integer, y = 1 and y = 9 yield the same result.

datatype_icon

x rotated left by y

The result of the rotation. The data type of this output is determined by the input data types.
